Careful and accurate identification and classification of organisms are of vital importance so that the extents of their harmful and beneficial properties are established. Since some of the members of tribe Archipini are pests of various crops, so this study was conducted with the aim to identify, describe, name and classify these species and also prepare illustrated diagnostic keys for their quick and authentic identification and efficient management. Study Design: Taxonomy of tribe Archipini. Place and Duration of Study: The collection of these tortricid moth specimens was done in districts Anantnag, Ganderbal, Kupwara, Kargil and Leh of J&K State during 2010-2012, while as _____________________________________________________________________________________________________ *Corresponding author: E-mail: [email protected]; Ganai and Khan; ARRB, 27(2): 1-16, 2018; Article no.ARRB.41606 their processing was performed during 2014 in Biosystematics Laboratory, Division of Entomology, Sher-e-Kashmir University of Agricultural Sciences & Technology of Kashmir, Shalimar, Srinagar- 190 025. Methodology: For this study, intensive and extensive collection-cum-survey tours were conducted to capture tortricid moth species from far-flung localities of different areas of Kashmir and Ladakh from March 2010 to November 2012. Since these moths being nocturnal in behaviour, their collection was done during night with the help of portable bucket type light traps fitted with 125 W mercury vapour lamp and mercury vapour lamp hung along a white cloth sheet secured to a wall or directly over a plain white wall to protect wings and scales from damage due to overcrowding during trapping in bucket of light trap. These specimens after collection from field were processed in laboratory. For preparation of permanent slides for wing venation, method proposed by Common (1970) and advocated by Zimmerman (1978) was followed, while as for studying male and female genitalia, the method suggested by Robinson (1976) was followed with slight modification. Results: Twelve Tortricid moth species belonging to six genera viz., Choristoneura Lederer, Archips Hubner, Pandemis Hubner, Clepsis Guenee, Neocalyptis Diakonoff and Homona Walker of tribe Archipini and sub-family Tortricinae were collected from Kashmir Himalaya and dealt with taxonomically. Overall, two species viz., Choristoneura pseudofumiferana and Clepsis kupwari are being reported as new to science. Besides, giving an illustrated account of new species, the taxonomic account of already known species has also been added to improve their diagnosis. Further, key to the presently examined species of all genera has been prepared on the basis of characters such as labial palpi, antennae, costal fold, anal fold, wing venation and male and female genitalic characteristics. Conclusion: In the Kashmir and Ladakh Himalayan region (North-west) of J & K state of India twelve species belonging to six genera viz., Choristoneura Lederer, Archips Hubner, Pandemis Hubner, Clepsis Guenee, Neocalyptis Diakonoff and Homona Walker of tribe Archipini have been collected during present investigation, out of which two species viz., Choristoneura pseudofumiferana and Clepsis kupwari are being reported as new to science. Further the reporting of two new species increased the number of species under genus Choristoneura Lederer from four to five and genus Clepsis Guenee from two to three in Kashmir zone of Jammu & Kashmir.

INTRODUCTION Archipini to date, based on morphology of the Japanese species, and found Ramapesiini to be Archipini were initially recognized by Pierce and paraphyletic to a monophyletic Archipini. Metcalfe [1] based on the presence of an According to Brown [8] Archipini is the largest elongated signum and a bulbous capitulum in the tribe within the Tortricinae, with more than 1,600 female genitalia, however, several of the taxa described species in 150 genera. Its members placed in the tribe by them lacked this character are present in all regions but are uncommon in and the circumscription of the group was based the neotropics. Most are polyphagous leafrollers, solely on the British fauna. Common [2] and this tribe contains many pests, such as the subsequently had difficulty applying Pierce and light brown apple moth (Epiphyas Metcalfe tribal arrangement to the Australian postvittana Walker). A synapomorphy for the tortricids, which led him to broaden Archipini to group is the dagger-shaped signum in the female include several additional taxa lacking the corpus bursae. Following this characterisation, signum and/or capitulum. Horak [3,4] postulated the material collected from Kashmir Himalaya that Common’s concept of Archipini was have been found to belong Twelve species of six polyphyletic and divided the tribe into three genera viz., Choristoneura Lederer, Archips groups typified by Archips, Clepsis, and Hubner, Pandemis Hubner, Clepsis Guenee, Planotortrix. Razowski [5] briefly expanded the Neocalyptis Diakonoff and Homona Walker tribe to include the tribe Euliini but then removed belonging to tribe Archipini and sub-family the latter, as well as transferring taxa with a well Tortricinae.
